When a stepparent decides to adopt a child, one area that can be deeply affected is the status of grandparent visitation rights. There have been cases in California where stepparent adoption has led to the termination of existing visitation rights for grandparents. At Mattis Law, A.P.C., we guide families through difficult legal issues related to custody, parenting rights, and adoption.

What Is Stepparent Adoption?

Stepparent adoption is a legal process in which a biological parent’s spouse (the stepparent) adopts the child and assumes full parental rights and responsibilities. Once completed, the stepparent becomes the child’s legal parent, and the noncustodial biological parent’s rights are permanently terminated.

Common reasons for stepparent adoption include:

  • Formalizing the bond between stepparent and child
  • Replacing an absent or uninvolved biological parent
  • Granting legal authority for decisions involving schooling, healthcare, or inheritance

Legal Rights for Grandparents in California

California law recognizes the importance of maintaining relationships between grandparents and their grandchildren, particularly when a parent is absent, deceased, or estranged. Under California Family Code § 3104, a grandparent may petition the court for reasonable visitation if:

  • The court finds that the grandparent and child have a pre-existing bond that is in the child’s best interest to maintain, and
  • The visitation does not interfere with the authority of the parent(s)

Courts assess factors like:

  • The nature of the relationship between the child and grandparent
  • The role of the grandparent in the child’s upbringing
  • Any objections by the custodial parent
  • The child’s emotional needs

The Impact of Stepparent Adoption on Visitation Rights

Under California law, when a stepparent adopts a child, the legal relationship between the child and the biological parent’s extended family, including grandparents, can be terminated along with the biological parent’s rights.

That means:

  • The noncustodial biological parent loses parental rights
  • His or her parents (the child’s grandparents) lose legal standing to request or maintain visitation in most cases

This is often a surprise to grandparents who have played a significant role in the child’s life. The court’s rationale is based on the idea that the child is now part of a new, intact family and should be allowed to form uninterrupted bonds with the adoptive parent.

Can Grandparents Retain Visitation Rights?

California statutes provide some exceptions that allow grandparents to retain visitation after a stepparent adoption.

A Biological Parent Is Deceased

If the biological parent (whose rights are being replaced in the stepparent adoption) is deceased, the law allows the child’s grandparents to petition for visitation under Family Code § 3102.

In this case, the court must determine:

  • Whether visitation is in the best interest of the child
  • Whether visitation would disrupt the new family structure

Judges may consider whether the grandparent had a close pre-existing relationship with the child and whether the surviving parent supports continued contact.

Visitation Ordered Before Adoption

In some cases, grandparents may already have a court-ordered visitation schedule before the stepparent adoption. However, unless explicitly preserved, these rights do not survive once the adoption is finalized.

If a family anticipates a stepparent adoption and wants to preserve grandparent contact, legal counsel can explore negotiated agreements or specific judicial findings in advance.

Adoption Fraud or Misconduct

If the adoption process involved fraud, coercion, or improper procedures, a grandparent may have legal grounds to challenge the adoption or restore visitation through a separate legal action. These cases are complicated and require the involvement of experienced family law counsel.

Structuring Visitation Agreements Before Adoption

If your family is considering stepparent adoption and you wish to preserve grandparent relationships, the best time to address this is before the adoption is finalized.

At Mattis Law, A.P.C., we help families explore open adoption-style agreements that allow for continued contact between the child and grandparents, even if not enforceable in the traditional sense. These agreements, while not always binding, can set expectations and avoid conflict later.

If a biological parent is consenting to the stepparent adoption, they may be able to negotiate terms that preserve grandparent involvement as part of the adoption filing or mediation process.

What to Do If You’re a Grandparent Facing Termination of Rights

If you’re a grandparent concerned about losing contact with a grandchild due to stepparent adoption, here are some important steps:

Consult a San Diego Family Law Attorney

California adoption and custody statutes are complex. Finding the right legal representation can make a big difference when it comes to successfully resolving custody and visitation issues.

Document the Relationship

Maintain a record of your involvement in the child’s life, such as photos, cards, school pick-ups, text messages, and any other evidence that shows an ongoing bond.

Act Before the Adoption Is Finalized

Once the adoption is finalized, options to preserve visitation become extremely limited. If you’re aware of an upcoming adoption, contact a San Diego Adoption lawyer immediately to discuss your situation.

Explore Mediation

Sometimes, mediation between the custodial parent and grandparents can lead to informal agreements for continued visitation, even if it’s not court-ordered.

What to Do If You’re a Parent Considering Stepparent Adoption

If you’re a biological parent seeking to have your spouse adopt your child, be proactive about managing relationships with extended family members.

  • Communicate openly with grandparents about your intentions
  • Consider written visitation agreements if the child has a strong bond with a grandparent
  • Discuss potential legal consequences with a family law attorney to avoid surprises down the road

At Mattis Law, A.P.C., we help parents build long-term custody and adoption strategies that align with their goals, while minimizing the risk of future legal conflict.
