Parentage Lawyers

Guiding You Through Challenging Times

Establishing legal parentage—formerly known as paternity—is one of the most important steps in protecting your relationship with a child.

Oregon’s new Parentage Act modernizes family law to recognize all families, including those formed through marriage, assisted reproduction, surrogacy, and LGBTQ+ parenting. 

At Gevurtz Menashe, our experienced Oregon parentage attorneys and paternity attorneys help clients establish, challenge, and protect legal parent-child relationships with clarity and confidence.

 

What Is Parentage? (Formerly Paternity)

“Parentage” refers to the legal relationship between a parent and a child.

Under Oregon law, parentage is no longer limited to biological fathers. Instead, it includes a broad range of legal relationships recognized regardless of gender, marital status, or how a child was conceived. 

Whether you are seeking a paternity test in Oregon, establishing legal rights as a parent, or navigating a dispute, understanding parentage is key to protecting your future.

Why Retain a Parentage Attorney

How to Establish Parentage in Oregon

Oregon law provides several ways to establish legal parentage, including:

  • Giving birth (with exceptions for surrogacy) 
  • Presumed parentage (such as marriage or committed relationships) 
  • Voluntary Acknowledgment of Parentage
  • Court-ordered parentage (paternity) cases
  • Adoption
  • Administrative child support orders
  • Assisted reproduction and surrogacy agreements 

Our Portland parentage attorneys guide clients through each of these pathways to ensure legal rights are properly established.

Presumed Parentage in Oregon

Oregon law may automatically recognize someone as a legal parent in certain situations, including marriage or similar family relationships. 

In some cases, even individuals who intended to parent a child together may qualify for presumed parentage. 

These legal presumptions can significantly impact custody, parenting time, and child support, and may be difficult to challenge without legal guidance.


Voluntary Acknowledgment of Parentage (AOP)

A Voluntary Acknowledgment of Parentage allows parents to establish legal parentage—without going to court.

Once signed and effective, this document has the same legal force as a court judgment. 

Because strict deadlines apply to rescind or challenge an acknowledgment, it’s important to consult an Oregon paternity lawyer before signing.


Parentage (Paternity) Cases in Court

When parentage is disputed, the court may decide the issue through a parentage case (formerly called a paternity case).

These cases may involve:

  • DNA or genetic testing
  • Disputes between multiple potential parents
  • Questions about intent in assisted reproduction cases

Courts consider not only biology, but also the child’s best interests and established relationships. 

Our parentage attorneys in Portland, OR and Vancouver, WA represent clients in complex and high-stakes parentage litigation.



DNA Testing and Parentage

DNA testing is often used to determine biological parentage and can create a presumption of legal parentage when results meet legal thresholds. 

However, under Oregon’s updated Parentage Act, biology is not always the deciding factor.

In cases involving egg donors, sperm donors, or assisted reproduction, genetic testing may not override legally established parentage rights. 

Assisted Reproduction & LGBTQ+ Parentage

Oregon law now provides strong protections for families formed through assisted reproduction.

  • Intended parents can be legally recognized—even without a genetic connection
  • Donors are generally not considered legal parents
  • Written agreements and intent play a critical role

This framework supports LGBTQ+ families, same-sex parents, and nontraditional parent structures, ensuring equal legal recognition. 


Surrogacy and Legal Parentage

Oregon now has a comprehensive legal framework governing surrogacy and intended parent rights.

When statutory requirements are met:

  • Intended parents are recognized as legal parents at birth
  • Surrogates do not have parental rights
  • Courts can issue pre-birth parentage orders

Our attorneys assist with surrogacy agreements, parentage orders, and fertility law matters to ensure compliance and enforceability.

Challenging Parentage in Oregon

Challenging paternity or parentage involves strict legal deadlines and complex standards.

In many cases:

  • Challenges must be brought within a limited timeframe (often four years)
  • Courts prioritize stability and established parent-child relationships

Exceptions may apply in cases of fraud, mistake, or competing parentage claims. 


Why Establishing Parentage Matters

Legal parentage affects critical rights and responsibilities, including:

  • Child custody and parenting time
  • Child support obligations
  • Inheritance rights
  • Medical and educational decision-making

Oregon’s Parentage Act prioritizes the child’s stability and well-being, alongside legal intent and family relationships.

Testimonial

“I highly recommend the Gevurtz Menashe team and specifically Shawn Menashe. While nobody wants to divorce, Shawn and his team followed my desire to stay out of court and coached me in helpful ways to create a fair settlement that worked for me and for my now ex-spouse. He told me up front how much it would cost and it came in under that estimate. When appropriate, he handed me off to another highly capable member of the team for certain pieces of the process. Shawn and team made a very difficult and stressful life situation manageable and I'm grateful.”

Frequently Asked Questions

Paternity refers to the legal establishment of a child's biological father and is used when determining parental rights and responsibilities.

The court may consider your refusal as evidence against your claim and may rule that you are the legal father. Essentially, the court’s left to make decisions about parental rights and responsibilities without the benefit of a paternity test.

The father gains legal rights to custody and visitation with the child as well as the right to participate in important decisions affecting the child's life. He also becomes financially responsible for the child.

Yes, a paternity test can be done before the child is born through a procedure called prenatal paternity testing. As this testing may have risks, it should be discussed with a healthcare professional.

You can petition the court to issue a new order reflecting the updated information on paternity.

A paternity lawyer can provide legal guidance and representation throughout the paternity case. They can help you understand your rights and responsibilities, gather evidence to support your claim, and present your case in court. They can also assist in negotiating agreements with the other party and ensure your best interests and the child's well-being are prioritized.
