I am moving house to our holiday home which will be a permanent move. I kept the deeds of our Dublin home here in the holiday house, at the bottom of a fire proof filing cabinet, which wasn't locked as we had lost the key. The deeds were at the bottom of a pile of small boxes of old photographs, so would require a bit of rummaging to get them. I periodically checked that the deeds were there - the last time being when I was here on holidays for two weeks in July. Yesterday evening, I was going through paperwork from my Dublin house move, and came across bills for an extension and attic conversion and new boiler in 2011, which I wanted to put with my deeds for my Dublin home, in case we ever sell it, and there is a capital gain on it, which I can use these building costs to offset. However, when I went to the filing cabinet the deeds weren't there - searched all over the house, and nothing. Two people knew they were there, but the house is used about three times a year by friends - not for payment - and they bring friends with them. Do I need to have these deeds reconstituted - they are Land Registry? Is there a danger that someone can use my deeds for a fraudulent property transaction - put in their own names, take a mortgage out on them? What is the best course of action here?
