My question is, how do we find out if she is still alive and where would the house deeds be held. Do we contact the solicitor who dealt with our side of things at the time (they are also 500 miles away) and will they have the house deeds?
- House Deeds
Why do you want the house deeds?
If any mortgage on the house was paid off a long time ago, it is possible that either the solicitors who dealt with the mortgage originally hold the deeds (which may not necessarily be the solicitors you used) OR that the deeds were given to your inlaws when the mortgage ended. Things are done differently now (all electronic) but if it was a long time ago, there would have been paper deeds which are normally held by the solicitors. When the mortgage is paid off, you can if you want have the deeds given to you or you can leave them with the solicitors for safe keeping.
It's obviously worth asking the solicitors. I'm not sure why it's relevant that they are 500 miles away. They are solicitors so they will have a telephone number and an email address!
If you are asking them whether they hold deeds to a property that you/yr husband/brother own, they will answer that. They won't be billing you £300 an hour to answer a basic question about what documents they hold.
2.Is she still living in the house?
The obvious thing to do in the first place is to send someone round to knock on the door and see who is there.
There are lots of different types of professionals you could get to do this from process servers (not that they would be serving legal proceedings) but this is a job they could do, to private investigation agencies to solicitors and so on.
I'm assuming you don't know any neighbours there but do you have any friends/relatives who are closer who could go?
Beyond that, if you are talking about the value of substantial property, I'm guessing it is worth a 500 mile trip yourself. I mean it's not like it's Australia is it?
The Proclaimers would have been there in a moment!
3.Is she still alive?
Start with a basic google search using her name variously first name and surname in inverted commas (so it searches for that exactly) together with her address/location in various permutations; same again with her full name including middle names; same again for both including the words (separately) obituary or funeral. Try this also on local papers/local news website for the areas.
Then as has been suggested you can do a probate search - but this would require her to have people who had applied for probate on her behalf.
Death certificates are public documents so you can search for and obtain copies of these yourself but you will need basic information about the person you are searching for.
