Most women freeze their eggs to preserve options for their future fertility. Others may choose to freeze embryos, which are created when an egg is fertilized by sperm. Since embryos are further developed than eggs, there’s more biologic information available and preimplantation genetic testing (PGT) can be performed, making it easier to predict success rates for a future pregnancy. Embryo freezing may be the preferred option for women who already know they want to use a specific partner or donor’s sperm.
While embryo freezing can be a great option for some, it also introduces additional layers of complexity. Unlike eggs, embryos involve genetic material from two people, which means both parties have legal and ethics interests, and thus, courts may treat them differently. As relationships evolve, partners separate, or priorities shift, decisions about embryos can become emotionally and legally charged, especially when there isn’t a clear agreement in place from the start.
This is why the legal foundation you set at the beginning of your fertility preservation journey matters just as much as the medical one.
There are two documents that can assist in your journey of IVF, surrogacy, donation, and when you create embryos:
Clinic Embryo Disposition Forms which are forms provided by the clinic to intended parents prior to creating embryos.
Reproductive Estate Plan (REP) which is drafted by an attorney as a contract between intended parents.
What happens if a couple separates or divorces?
Most states require mutual consent for an embryo transfer. This means:
One partner cannot use embryos without the other’s consent
Courts often prioritize a person’s right not to procreate
Many couples assume the disposition forms will control what happens, but those forms are typically administrative, very limited in scope, and not legally binding. So, they often don’t resolve disputes when relationships change.
If the couple has an embryo agreement or a REP, courts usually defer to it. Without one, decisions become unpredictable and can lead to prolonged legal conflict. Embryos may remain in storage indefinitely if the involved parties don’t consent to either use or destruction. Clinics may refuse to act at all without a court’s decision.
Can one partner use the embryo alone?
Usually, no. Courts rarely allow one person to use embryos over the other’s objection, as this forces parenthood.
A notable exception is Hecht v. Superior Court (California), where the court allowed posthumous use of sperm only because the deceased partner left explicit written instructions. Without that clear documentation, his partner would most likely not have been permitted to proceed.
When one partner dies, courts require specific, verifiable proof of intent. Generally this goes beyond discussions. Courts look for wills, written directives, or REPs. Without them, surviving partners are almost always denied permission to use embryos or gametes, requiring destruction of the embryos or gametes.
Why is your legal plan just as important as your medical plan?
Your legal agreements are the one place you can return to when circumstances shift. These documents create clarity, stability, and protection so your family-building goals are honored no matter how life unfolds. They protect both parties, your reproductive autonomy, family-building goals, and your peace of mind.
Before creating or freezing embryos, it’s essential to have a legally enforceable structure/documentation that protects your reproductive intent in every scenario. This type of legal document would either overrule the clinic embryo disposition form or act as a clarifying pillar behind the clinic embryo disposition form.
Fertility is one of the most meaningful journeys people take. The medical care, the emotional support, and the legal planning all work together. When these three areas are aligned, people can move through the process with peace of mind.
