Legal Question in Family Law in California

If you are an unregistered partner, the division of your property would not be subject to California family law codes. This matter would be a civil litigation issue. Please contact a civil litigation attorney to explore your legal rights.

Ms. Kock is right. You are not legally a "domestic partner" at all if not registered. You are just roommates. Whether or not you are entitled to reimbursement will depend on the same considerations as if you provided the money to a roommate. You will have to go over all the facts and circumstances of the situation to determine whether the "investment" formed a de facto partnership, or was a loan or other true investment, or under some other theory is reimbursable.
