Facing a complex family law matter involving more than just you and your spouse? When legal disputes extend beyond the immediate parties—like a third party claiming a financial interest—understanding tools like a joinder can be critical. At Barli Law LLC, we’re here to explain what a joinder is, when it applies, and why it may be essential to resolving your case effectively.
Understanding Joinder in Family Law

In family law, a joinder is the legal process of adding a third party to an existing case. This allows the court to hear from all parties who have a legal interest in the outcome of the matter—ensuring a complete and enforceable resolution.
Unlike typical divorce proceedings between two spouses, some family law cases involve outside parties—for example, an ex-spouse’s retirement plan, a jointly owned property with a relative, or a third party seeking custody rights. In these scenarios, a joinder ensures all voices are heard in one proceeding, rather than in multiple, separate lawsuits.
When Is a Joinder Necessary?

Joinders come into play when someone outside of the initial case has a legal stake in the outcome. Here are a few common examples:
- Retirement or Pension Plans: When dividing assets in a divorce, the court may need to join a pension or retirement plan administrator to properly divide those benefits.
- Property Disputes: If a third party (like a relative or business partner) claims ownership in marital property, their rights need to be addressed.
- Custody or Parentage Cases: A non-parent (such as a grandparent or guardian) may seek custody or visitation, making their inclusion in the case legally relevant.
By including these parties through a joinder, the court ensures fairness, transparency, and efficiency in resolving the matter.
Why Joinders Matter

Joinders play a crucial role in the legal process because they:
- Protect the rights of all interested parties.
- Prevent separate lawsuits about the same property or issue.
- Promote judicial efficiency, saving time and resources.
- Allow for complete, enforceable court orders that reflect the full scope of the legal matter.
At Barli Law LLC, we assess whether a joinder strengthens your position or protects your interests in a complex case.
How the Joinder Process Works

The process of adding a party to your case generally involves the following steps:
- Filing a motion (or request) with the court to initiate the joinder.
- Serving the new party with notice and relevant court documents.
- Allowing time for response or objection from the joined party.
- Court review and ruling, determining whether joinder is appropriate.
Depending on the case, you may also need to file additional legal forms, such as a Joinder Pleading or a Summons. Our legal team will guide you through each step, ensuring everything is completed accurately and on time.
Challenges to Consider

While joinders can be powerful tools, they also come with complexities. It’s important to weigh the following:
- Potential delays due to additional court proceedings.
- Increased legal costs or complications.
- Opposition from the party being joined, which may lead to further disputes.
