Thank you for the quick feedback, I had read about this. Is that period also valid if I was not contactable i.e. the DCA did not have my address?

Hello, In a nutshell, I left the UK in 1990 to live in France, was unable to keep up mortgage payments and unable to sell resulting in a repossession in 1991. A DCA chased me (I don't know whether they purchased the debt or were working on a commission basis), the last I heard from them was about 1997. Since 1999 I have been living in Italy and have rebuilt myself. Neither the DCA nor mortgage company have contacted me since 1997, but I do not think that they have my address. There are no CCJs listed against me at my last UK address. Is there anything that they can do now as I continue to be a non-resident? If my address became available is there anything that could be served against me? Thanks for any advice...
