Legal Question in Family Law in Texas

If your divorce is finalized, I don't see a problem.

You did not include some vital information - how big is this building?

If your ex is his new landlord -- what is the conflict?

Renting office space has nothing to do with your divorce.

There would be reason for an attorney to discuss his cases with his landlord.

If your case is on-going, perhaps you don't want your ex to see you coming to your appointments. That might be a valid concern. Talk to your attorney.

I rent in a huge office space. I have no idea who actually owns my building - some giant corporation.

Call your attorney and discuss it with your attorney. If you don't feel comfortable, then discuss firing your attorney and getting a new one. You can ask your attorney for a referral and an introduction to a new attorney. He should help you find someone and help you negotiate a reasonable new retainer since he created this problem.

You can call the State Bar of Texas & ask them. Perhaps they will have a different opinion when all the facts are brought out. If they do, then go with them. I could be wrong but I don't see why he would discuss your case with his landlord.

I assume that he would lock up your file each night in a file cabinet so your ex could not have access to your file.

Of course, if it's a really small building then perhaps my answer would be different. There are some facts that could make me change my mind�but you did not include them so I assume it's a regular office building - not a tiny shared office set-up.
