Somewhat bizarre situation LONG

When my dad brought his family over to the US from Iran, he bought a house (primarily for my grandmother) but my dad's sister, brother-in-law and their daughter lived there.  The agreement was that my parents bought the house and when it was sold, half would go to my parents and half split between the 3 children.  My parents paid for all the upkeep, insurance, taxes, etc.  The house was bout for about $199K and at today's market value, it "should " be about $500K. 

My grandmother died years ago, then my uncle died a couple years ago and on July 4, my aunt passed.  So their kids (1 of which is NOT good with money, the other 2 are responsible) made the assumption that since my aunt had no will, it would have to go through probate.  My sister found the deed at my parents house and in fact, my parents are listed as the owners on the deed, not my aunt and uncle which means my parents can sell the house as they see fit.  The one son who isn't good with money only wants his share of the money and even asked my dad for money.  Mind you, a collection agency actually tracked ME down and tried to get me to give up my cousin.  I told them to stop calling and I never heard anything else.  My dad told him "no" because he knew he would never see that money again.  My parents are very well off and have done a lot for my dad's family but my dad is 90 and in failing health.  He wants to make sure my mom has plenty to live on (believe me, she does). I agree with everything he has said and done.

The middle son (eldest is the one that is bad with money) wanted proof that the deed had my parents on it so they took a picture and texted it to him.  End of story.

So my dad told my cousin that they had to clear out the house because it was going to go on the market.  They have no idea that once my parents take out all the money they just paid for taxes, insurance, closing costs, etc. there really won't be much for the 3 of them to split but whatever.... He was going to take his time but my dad said no and that they had all of August to clear out the house which will be sold "as-is".  So he texted my dad yesterday and said the house is cleared out and the keys are in the mailbox!  WHAT?  My mom calls me because I live about 10 minutes from there to ask about some piece of furniture they assumed my son would want for his new apartment (my son doesn't want anything from there).  My mom isn't in the greatest health and so I said I would send dh over to get the keys and go in and make sure everything was  1. Cleared out and 2. the house was locked up.  He was going to leave the kitchen light on so it didn't look empty.  

So dh goes over after work and finds that somehow my cousin had the power turned off and while they did remove anything of "value".  So all the damn furniture is still in the house with a couple of exceptions.  The house smells because there's no a/c and while there isn't any food in the fridge or freezer, they still stink.  So now my parents have to pay someone to remove the furniture (that cost is coming out of the kids portion). Having a donation center come won't work because it takes months to get them to show up.  If  the power isn't turned back on, we are going to have a mold problem.  So my mom calls the power company to get it turned back on and they said they can't because they don't have a death certificate (which hasn't been issued).  We have no idea how my cousin cut the power if she isn't on the deed or account and my aunt and uncle weren't smart enough to give a POA.  Pepco said they will turn it back on when the final bill is paid.  My mom said "okay, how much?" and they said they don't have access to it.  I assume that's because it hasn't been generated yet.

My dh, my sister and I went last night to look around and my dh didn't even find half of the crap that is in the house.  There is a sunroom in the back but the door to the outside doesn't lock and the slider to the basement also doesn't lock.  We are concerned that someone will go in and strip the copper and anything else they can get to.  This house is not in a great neighborhood anymore. It is going to have to be a flip because there is so much work that needs to be done.

So my dad has been trying to get in touch with any of the 3 kids and "crickets".  They won't return his calls or texts.  They were nice to my dad until they realized that the money well has dried up. My mom needs the death certificate but she doesn't know if she can get access to it and I know it will take time to get it.  

What also sucks is my dd is getting married in October and we limited who was invited and they did make the list.  I will be interested in seeing if they decline the invite.
