If the seller files for bankruptcy for some reason, you have to hire a lawyer to protect your rights. 

I've got to find out if the remaining heir has a deed locked away somewhere in the Estate lawyer's office they used and I think Will Sifert is right that the property  might first have to get it legally transferred to the heir via deed but then again  the grantor in a Quit Claim Deed may not even be owner of the property, but in this case, including having previously talked to the Estate attorney, I know he if the only remaining heir that wanted it but now wants to surrender it as he doesn't want to pay the taxes and will never use it. 

What should I be asking my "highly recommended" lawyer? 

I'll contact my lawyer to get their advice as well and details on the paper work but I was hoping maybe I could get into contact with some NH landlords who have been through this before so I can learn more about what I should do and how the process works.

He only let's his broker and lawyer handle the case.They do not give out to many reasons.THANK YOU ALL FOR ANSWERS

I have seen nothing to even indicate he opened the lawyers attachment.

We use KKOS (lawyers) and kohlereyrecpas.com (CPAs)

Well if you really want to do it right, you should speak to a local PM or lawyer who has done it before.

I'm not a lawyer or CPA.

Talk to a lawyer, but I don't think you can retroactively collect for a pet deposit, that seems like it could get messy.
