Question: Can I pursue a claim against my deceased friend’s ex-husband for repayment of funds I used to install an air conditioning unit based on an oral promise made by my friend?

Answer: Pursuing a claim against your friend's ex-husband for repayment of the air conditioning unit you installed based on an oral promise from your friend is unlikely to be successful. Key issues, in this case, include the lack of a written agreement between you and your friend and the fact that the ex-husband was not a party to any such agreement. Generally, in contract law, only parties to a contract are bound by its terms. Additionally, oral agreements can be difficult to enforce, especially in matters involving real estate, where written contracts are typically required to ensure enforceability. Without direct involvement or an agreement with the ex-husband, a court is unlikely to find him liable for the repayment of the expenses incurred. It would be advisable to consult with an attorney who specializes in contract law or estate law for a detailed assessment of your case and any possible legal remedies.
