Your credit score is reflective of your debt repayment history with your creditors. If you are not able to pay back all or portions of your debts, then your credit score will suffer. Declaring bankruptcy in itself will not necessary “ruin” your score but certainly once you declare bankruptcy your score will reflect this fact. Your score will also reflect the fact if you are late paying your debts or simply default on your payments. Once you have completed bankruptcy for a Proposal then you can make a clean financial start and start to rebuild your credit.
