Can I get ownership on the house I’m living in by paying property taxes?

Dear Ms. Gillen: Unfortunatey, you have no legal right to the property, because, as you noted, your name was never on the deed.  You might have a claim for what is called an equitabe lien because of your contribution to property taxes for the past 7 years. An equitable lien usually involves someone engaging in egregious or fraudulent conduct, which does not seem to be the sitution you described.  On the other hand, such a lien can be imposed when there has been unjust enrichment(i.e. you've paid the taxes to benefit someone else). However, your claim was probably stronger when your boyfried died, or at least when his mother died before the sister inherited the property.   This is really a civil matter and not a family law matter, but you should at least consult with an attorney to determine if you have a claim and the value of same. It is likely that, at best, you might be able to recover some of the property taxes you paid.   Best of luck, Cindy S Vova Law Offices of Cindy S. Vova, P.A.
