You could do what I have done Brickkicker and scan the deeds onto your PC then transfer the files to a memory stick which you carry everywhere with you.
Whilst you are at it, you could also keep photos of each room in your home (in case of fire) scans of insurance policies, important documents such as Birth certificates, Passports, Driving Licence, Share certificates, Credit Card numbers and Emergency numbers etc etc.
That way if disaster strikes you will at least have the records you need.
But.......... make sure the memory stick is password protected!
