Maryland has no restrictions on at-home paternity testing. You can order a kit online, collect DNA samples at home, and mail them to a lab without a doctor's order or any state-level permission. If you want a private answer about biological paternity, the process is available to anyone in the state.
What sets Maryland apart is the gap between establishing paternity and getting parental rights. In most states, once a man is legally recognized as the father — whether through a voluntary acknowledgment or a court order — he gains standing to seek custody and visitation as part of the same proceeding. Maryland works differently. The state's Declaration of Paternity establishes legal fatherhood, but it does not automatically grant custody or visitation rights. A father must petition the court separately for those. This distinction surprises many Maryland fathers who assume that signing the Declaration at the hospital puts them on equal legal footing with the mother. It doesn't — not until a separate custody order is in place.
Below we walk through Maryland's paternity laws under the Family Law Article §§ 5-1028 through 5-1038, how the Declaration of Paternity works, the rescission timeline, court-ordered genetic testing, and how at-home DNA testing fits in.
How Maryland Law Defines Paternity
Maryland's paternity laws are found in the Maryland Family Law Article, §§ 5-1028 through 5-1038. These sections govern how paternity is established, challenged, and enforced in the state.
Marital presumption: If a child is born during a marriage, Maryland law presumes the husband is the biological father. This presumption also applies if the child is born within 300 days after the marriage ends. The presumed father has all legal rights and obligations from the start — child support, inheritance, and the ability to seek custody. Overturning the marital presumption requires a legal proceeding, typically supported by DNA evidence.
For unmarried parents, there is no automatic presumption of paternity. The biological father must take affirmative steps to establish a legal relationship with the child. Maryland provides two main paths: signing a Declaration of Paternity or going through the court system under the Family Law Article. For a general overview of all the ways paternity can be established, see our guide on how to establish paternity.
Voluntary Declaration of Paternity in Maryland
The most common way for unmarried parents to establish paternity in Maryland is through the Declaration of Paternity. Maryland uses the term "Declaration" rather than "Affidavit" or "Acknowledgment."
Maryland hospitals are required to provide the Declaration of Paternity form to unmarried parents at the time of birth. Both parents sign it voluntarily. If the parents don't complete the Declaration at the hospital, they can sign one later through a local Department of Social Services office. The signed Declaration is filed with the Division of Vital Records, and the father's name is added to the birth certificate. Once filed, the Declaration creates a legal presumption of paternity.
Key details about Maryland's Declaration of Paternity:
- Both parents must sign voluntarily. Neither parent can be coerced. Both receive written notice of the legal consequences before signing.
- It doesn't have to happen at the hospital. If parents didn't complete the Declaration at birth, they can execute one later through their county Department of Social Services and file it with the Division of Vital Records.
- Once filed, it has the same legal effect as a court order for paternity purposes. The man listed on the Declaration is the legal father for purposes of child support, inheritance, and other obligations.
- It does NOT grant custody or visitation. This is the critical Maryland distinction. Signing the Declaration establishes that you are the legal father, but it does not give you any right to physical or legal custody. A father must file a separate petition in circuit court to obtain custody or visitation rights.
If you're unsure whether you should sign, consider getting a private answer first. A home paternity test costs $79 and gives you results in days. Those results won't hold up in court, but they can help you make an informed decision before signing a legal document that carries real consequences — especially in a state where that document doesn't automatically come with parental rights attached.
Rescinding or Challenging a Declaration of Paternity
Signing a Declaration of Paternity in Maryland is a serious legal step, and undoing it is harder than most people expect.
The 60-Day Rescission Period
Either parent can rescind the Declaration of Paternity within 60 days of the date it was signed. This is a federal requirement under 42 U.S.C. § 666(a)(5)(D)(ii) that applies nationwide, and Maryland follows it. During this window, you file a rescission with the Division of Vital Records, and the Declaration is voided. No court hearing is needed.
Court Challenge After 60 Days
Once the 60-day window closes, the only way to challenge a Declaration of Paternity in Maryland is through a court proceeding. The person challenging it must demonstrate fraud, duress, or material mistake of fact.
Maryland courts evaluate these challenges case by case. A DNA test showing the man is not the biological father is strong evidence of a material mistake of fact, but the court will also consider the circumstances — how long the father-child relationship has existed, whether the father acted in reliance on the Declaration, and the child's best interests. The longer you wait to challenge, the harder the path becomes.
If you have any doubts about biological paternity, act inside those first 60 days. A home paternity test can give you a private answer in less than a week. Once the window closes, the legal path gets significantly harder and more expensive.
Maryland's Paternity Establishment Process
When paternity can't be resolved through a voluntary Declaration, Maryland law provides a formal court process under the Family Law Article §§ 5-1028 through 5-1038.
Who can file a paternity action in Maryland:
- The child's mother
- A man alleging to be the biological father
- The child or the child's representative
- A state's attorney
- The Maryland Department of Human Services
A paternity action in Maryland can be filed at any time before the child turns 18. There is no statute of limitations that prevents the mother, the alleged father, or the state from filing during the child's minority.
Once a paternity action is filed, the court can order genetic testing, hear testimony, and issue a determination. If the court finds the man is the biological father, it will enter a paternity order establishing all legal obligations — most critically, child support. However, remember the Maryland distinction: a paternity order alone does not grant custody or visitation. The father must petition separately for those rights.
Court-Ordered Genetic Testing in Maryland
When paternity is disputed in a Maryland court proceeding, genetic testing is central to resolving it. Under Family Law § 5-1029, the court has authority to order the mother, the child, and the alleged father to submit to genetic testing.
The process:
- Any party to the paternity action can request genetic testing, and the court can order it on its own motion.
- Testing is performed by an accredited laboratory following chain of custody procedures. Samples are collected at an approved facility with ID verification, photographs, and documented handling.
- If the test results show a probability of paternity of 99% or greater, Maryland law creates a rebuttable presumption that the man is the father.
- The results go directly to the court and are admissible as evidence.
Refusing a court-ordered test: If someone refuses to submit to court-ordered genetic testing in Maryland, the court can draw an adverse inference — meaning the judge can presume paternity based on the refusal. The court also has the power to hold the person in contempt. Refusing the test doesn't make the case go away. For more on this topic, see our article on what happens if you refuse a paternity test.
Court-ordered testing is a different process from at-home testing. For a detailed look at what to expect, see our article on court-ordered paternity tests.
Maryland Child Support Administration
Maryland's child support program operates under the Child Support Administration, a division of the Maryland Department of Human Services. The program is the state's Title IV-D child support enforcement system, administered at the county level through local offices of child support enforcement.
The Child Support Administration can:
- Establish paternity for children born to unmarried parents
- Arrange genetic testing when paternity is in question
- File paternity actions on behalf of the state
- Establish, modify, and enforce child support orders
If a custodial parent applies for child support and the father hasn't been legally established, the IV-D program will initiate the paternity process. This typically includes requesting genetic testing from the alleged father. If he doesn't cooperate, the case moves to court.
These services are available at no cost to the custodial parent in IV-D cases. For Maryland residents who can't afford a private attorney, the Title IV-D program is often the most practical path to establishing paternity and getting a support order in place. Information is available through the Maryland Department of Human Services website or your county child support enforcement office.

At-Home vs. Legal Paternity Testing in Maryland
Maryland places no restrictions on at-home DNA testing. Unlike New York, which requires a licensed physician to order genetic tests, Maryland allows you to purchase a home test kit, collect cheek swab samples yourself, and mail them to a lab. No doctor's order, no state approval.
But there is a clear distinction between the two types of tests:
At-home paternity test: A private test you collect yourself. You swab cheeks at home, mail the samples back, and get results in a few days. The science and accuracy are identical to a legal test. However, because there is no chain of custody — no third-party verification of who provided the samples — Maryland courts will not accept home test results as evidence. Home testing is for personal knowledge only.
Legal paternity test: Follows chain of custody protocols. A trained professional collects samples at an approved facility with government-issued ID verification, photographs, and tamper-evident packaging. The results are admissible in Maryland courts for paternity actions, child support, custody, and birth certificate amendments.
A lot of people start with a home test. It's faster, private, and far cheaper than legal testing. If the results confirm what you expected, you walk into the legal process with better information. If they surprise you, you can rethink your plans before spending money on attorneys and court filings. We cover the differences in detail in our comparison of home vs. legal paternity tests.
How At-Home DNA Testing Works
The DNA testing process is the same whether you're in Maryland or anywhere else in the country:
- Order your kit. You can order a home paternity test kit from US Diagnostics Center for $79. The kit ships to your Maryland address and includes a prepaid return envelope for mailing your samples back.
- Collect samples. The kit includes cheek swabs for the alleged father and the child. You rub the swab on the inside of each person's cheek for about 30 seconds. No blood, no needles, no pain.
- Mail samples back. Seal the samples in the provided packaging and drop the prepaid envelope in the mail.
- Lab analysis. Once the lab receives your samples, processing takes 2-3 business days. Our lab analyzes up to 28 genetic markers — well above the industry standard of 20 or more markers.
- Get your results. Results are delivered securely online. You'll see either an inclusion (99.99% or greater probability of paternity) or an exclusion (0% probability).
The mother's sample is not required but can strengthen the analysis. A mother's kit can be added during checkout if you want to include it. Express result options are also available during checkout for faster turnaround.

Frequently Asked Questions
Can I use a home paternity test in a Maryland court?
No. Maryland courts require chain of custody documentation for DNA evidence to be admissible. A home test doesn't include witnessed collection, ID verification, or tamper-evident sample handling. Home test results are accurate for personal knowledge, but they won't be accepted as evidence in any Maryland legal proceeding. You would need a legal paternity test with full chain of custody for court use.
Does signing a Declaration of Paternity in Maryland give me custody rights?
No. This is one of the most misunderstood aspects of Maryland paternity law. The Declaration of Paternity establishes legal fatherhood — it creates obligations like child support and rights like inheritance. But it does not grant custody or visitation. A father must file a separate petition in circuit court to obtain custody or visitation rights. Until a custody order is in place, the mother has sole custody by default in Maryland.
How long do I have to rescind a Declaration of Paternity in Maryland?
You have 60 days from the date the Declaration was signed. During that window, you can file a rescission with the Division of Vital Records and the Declaration is voided — no court hearing needed. After 60 days, the only way to challenge it is through a court proceeding where you must prove fraud, duress, or material mistake of fact. If you have doubts about biological paternity, act quickly.
Who can file a paternity action in Maryland?
Under the Family Law Article §§ 5-1028 through 5-1038, the mother, a man alleging to be the biological father, the child (through a representative), a state's attorney, or the Maryland Department of Human Services can file a paternity action. The action can be filed at any time before the child turns 18.
Does Maryland's IV-D program provide free paternity testing?
In IV-D child support cases, yes. The Child Support Administration, operating under the Maryland Department of Human Services, can arrange genetic testing at no cost to the custodial parent as part of establishing paternity for a child support order. Contact your county child support enforcement office or the Maryland Department of Human Services to start the process.
What if the presumed father is not the biological father in Maryland?
If a child is born during a marriage, the husband is presumed to be the father under Maryland law. This presumption also applies within 300 days of divorce. Overturning the marital presumption requires a court proceeding and typically DNA evidence. The court will consider the circumstances, the length of the father-child relationship, and the child's best interests. A home paternity test can give you a private answer, but overturning the legal presumption requires going through the court system with a legal test.
