Poldara,
You should see what Tanager have to say for themselves before embarking on this route. From what I gather, in your particular case, (which is unusual) Tanager DAC do not have a valid legal charge secured on your property (although registered as owner of the charge with the PRA), as the owner of the charge was registered in the PRA as the Governor and Company of Bank of Scotland on a date after all charges transferred by operation of law across to BOSI, which happened in 2004. In 2007, the Governor and Company of Bank of Scotland ceased to exist. A bit of a legal quagmire for Tanager. They will argue that they bought the contractual rights of the loan to which you purchased your property and as such, may seek to pursue you by way of summary judgment. However, that being said, who gave BOS Plc the right to sell the contractual rights of your loan to Tanager when they may never have had those contractual rights in the first instance, seeing that these contractual rights may have remained with GCBOS. Definitely a right mess.
