The Short Answer

If a Florida mortgage lender refuses to let you “assume” the loan after a parent’s death, the practical risk is that the loan can go into default if payments stop—leading to foreclosure—and anyone living in the home (like a family friend) may ultimately face eviction after a foreclosure sale. Separately, even if you are the only child, a handwritten will and “no formal probate” often means you may not yet have the legal authority the lender wants to recognize you as the person entitled to deal with the property and the loan.

What Florida Law Says

In Florida, a will generally does not establish title or the right to possess the decedent’s property until it is admitted to probate. That matters because mortgage companies typically require proof of legal authority (and the correct chain of title) before they will discuss assumption, loan modification, payoff, or other options with an heir.

The Statute

The primary law governing this issue is Fla. Stat. § 733.103.

This statute establishes that, until a will is admitted to probate, it is ineffective to prove title to (or the right to possession of) the decedent’s property—often a key reason lenders refuse to process an “assumption” request from an heir.

Also, if the estate has potential assets (like unpaid disability benefits), timing can matter because Florida imposes hard limits on claims against estates. See Fla. Stat. § 733.710 (a 2-year limitation that can bar many claims), while still preserving a mortgage lender’s lien/foreclosure rights.

Why You Should Speak with an Attorney

Even when you are the only surviving child, applying the rules to a mortgaged home is rarely simple—especially where a handwritten will exists but no probate has been opened, a third party has been making payments, and a non-owner occupant may be displaced. Legal outcomes often depend on:

• Strict Deadlines: Estate-related rights and claims can be time-sensitive. Florida’s 2-year limitation in Fla. Stat. § 733.710 can bar many claims, while the mortgage lien can still be enforced through foreclosure.
• Burden of Proof: Lenders often require legally reliable proof of who has authority to act (and who owns the property). Under Fla. Stat. § 733.103, an unprobated will generally won’t prove title/right to possession—so the lender may refuse to deal with you until probate steps are taken.
• Exceptions and Competing Interests: Issues like homestead status, the validity of a handwritten will (Florida generally requires will execution formalities), occupancy rights of a friend in the home, and whether disability benefits are payable to the estate can change the strategy and the risk.

Trying to handle this alone can lead to a preventable foreclosure timeline, loss of leverage with the lender, or mistakes that complicate title—making it harder to sell, refinance, or stabilize housing for the occupant.
