Is there a Kentucky statute requiring an executor to prepare an inventory of assets?
Is there a KY statutes # for the executor to prepare an inventory of assets? I was informed at the attorney's office, there wasn't any law that required me to have this information. I am an heir to my Mother's estate. I have never been notified of any court dates to settle her estate. This has been all hush hush from the beginning with my brother and the attorney.
Is the 1971 joint will enforceable in Pennsylvania despite a later will?
My maternal Great aunt and Uncle made a will together in 1971. The lawyer drew up one document that they each signed, had witnessed and notarized according to PA law. The will stated that when one spouse passed, the remaining spouse would get the house, etc and when that spouse passed everything (really all they have is the house) would go to my sister and I. First my Great Aunt passed. When my Great Uncle passed last year, the person taking care of him, (And I use that term very loosely) (a cousin) produced a will that showed that my sister and I would get nothing and she would get everything. It was dated 16 days before his death. First, the 1971 was a joint will and I wanted to know if it is still valid and could not be changed. Second, the will was dated 16 days before his death and she never notified us. In fact she put it all in motion using her own attorney to come to the house etc. My uncle would never had done this and this women was his dead wife's sworn enemy. We were going to try to prove undue influence. But then I read about joint wills. Second, two years before she had the same attorney draw up a will leaving the house to us and she got the furniture. My uncle refused to sign it letting the 1971 will stand. Question: is the joint will in 1971 enforceable and the one she has dated 16 days before his death invalid in PA? Or do we need to prove undue influence?

Am I liable for my husband's car loan after his death?
My husband worked primarily in Tennessee. While there about 5 years ago he solely purchased a vehicle and financed it with a Bank. He let the collision insurance lapse stating later to me that he thought the bank would automatically insure it and add the expense to the loan amount. About 3 years ago he was in an accident where the vehicle was a total loss. He defaulted on the payments and ultimately the account was taken by a collection agency. About 2 years ago we were contacted by the collection agency and my husband started a payment arrangement with them. There are still about $6000 owed. When I spoke to the collection agency they said that they could not provide me with any records of previous payments - that all they can provide is the amount now owed. My husband recently passed away - within the last week. Will I be liable to finish paying this loan? Please advise.
