Hi Emma,(posted 7150 days ago)We were advised that once either party has made a payment they admit liability for all parties unfortunately. However, depending on whether your boyfriend has any assets (i.e. a house etc.) B&B may accept your offer - as David says they can chase for whole amount and can treat parties differently when it comes to settling. B&B are the worst building society to deal with unfortunately - believe me my husband & I know from experience!!
