Mrs. Devoted Hubby has a few legal considerations regarding the property in question:

1. Enforceability of Agreement: The written statement given by Mr. Hubby may constitute a binding agreement, especially if Mrs. Hubby has provided consideration (payment of the mortgage). Under contract law, for an agreement to be enforceable, it must include an offer, acceptance, and consideration. Since she paid the mortgage as per their agreement, she may have grounds to enforce the transfer of the house.
2. Equitable Interest: Even if Mr. Hubby refuses to transfer the property, Mrs. Hubby may argue that she has acquired an equitable interest in the house because she has contributed to its upkeep (by paying the mortgage). Courts often recognize equitable interests in property, especially when a party has acted to their detriment based on a promise.
3. Divorce Proceedings: In the event of divorce, the courts generally have the power to divide property fairly between spouses. If Mrs. Hubby can demonstrate that she contributed to the property through mortgage payments, she may be entitled to either ownership of the property or a financial settlement that reflects her contributions.
4. Legal Representation: Mrs. Hubby should consider seeking legal advice or representation to protect her rights and ensure her interests are represented during the divorce proceedings. This will help her navigate potential disputes regarding property and financial matters effectively.

Explanation:
Mrs. Devoted Hubby has several legal avenues to explore regarding the transfer of the house and her rights as a spouse. The situation is complicated by the impending divorce, but the existing agreement and her contributions can provide a basis for her claims.
