I have recieved by accident my original house deeds for a house i have a morgage for, and have been paying for some months. But since i have my original deeds does that mean the house is mine outright?
No - Deeds are irrelevant now, all the info is stored electronically by the Land Registry. Lots of banks and building societies have returned the paper deeds to the house owner, I have mine.
I assume your house is registered (has a title number).
If so, when the mortgage was put into place the legal charge deed would have been sent to the Land Registry with any other relevant docs at the time (eg transfer deed if you purchased it at the same time) and the charge is registered on your title along with any appropriate restrictions.
When your mortage is paid off the lender will normally send form DS2E to be Registry unless you redeem it on a sale or remortage etc... and the other appropriate form will be sent direct to the Land Registry or via your solicitor to remove the charge from the register.
Sorry, that should be DS2E to be sent to the Land Registry.
Keep your deeds somewhere safe and preferably fireproof or get your solicitor to keep them safe, can be useful in a land dispute etc...
As so much land is registered nowadays many banks do not want to keep all the old papers they used to store when deeds were the only proof of ownership and return them so they don't have to keep on storing them.
