Hi there, I went bankrupt a few years ago and can share my experience. I was single at the time so a different situation.
It wasn't humiliating at all, much easier and more sort of 'professional' than I thought. Remember that the people dealing with it are doing it ever day, so although it feels massive to you it's not to them.
You do have to make a repayment plan. They ask you to fill in a form with all your outgoings and income and they work out what is reasonable to repay. I would recommend massaging your details on this form. For example, you can include needing to buy smart clothes for work if you have a job, and regular haircuts. If you have pets, include insurance and food. If you have children, add in everything you can possibly think of. Round everything up, because while they might knock you down a bit they aren't going to help you out in the other direction.
You obviously can't round up things like rent/mortgage as they might ask for proof of that. Likewise with income if you work.
They then do the maths on your income and outgoings and suggest a realistic repayment plan. In my experience, it was genuinely realistic. They dont assume you can feed yourself on a pound a day or anything like that! You then pay this fixed sum each month to one place, so it's easy to manage, and they divide it up between your creditors. Your creditors can no longer chase you. They won't get all their money back but they will get some. You will feel a huge sense of relief, I'm sure.
The length of time you pay back for can vary, I think I did three years. It might be less but I think it can be up to 6 years in very serious cases. Then everything left to pay disappeared. I think it's a good system as obviously you should be repaying, but if it simply isn't feasible then bankruptcy allows you to make reasonable repayments rather than running away from your debt entirely.
I think they do take household income into account, so for example if your DH earns very well then it is assumed he can cover more of the family costs, but the bankruptcy would be personal to you, and should not directly affect him. In reality of course it has a knock on effect on him. CAB will be able to advise further on this. Maybe the Martin Lewis website would also have good info?
You do have to declare on various forms if you are or have ever been bankrupt. For example, when renting a house a few years later I told the truth about this even though I was no longer bankrupt and was fairly sure it would no longer show on my record. The landlord appreciated the honesty and let to us anyway. Obviously some would run a mile.
Your credit rating will take a huge hit but, several years later, mine is totally back to normal.
I wish I'd done it sooner, my debts related to family business rather than my own life (basically I incurred significant debt on behalf of others) and I spent a long time juggling things to try to keep up, but it simply wasn't sustainable. You don't have to feel good about doing it but you need to look at your life and see how you can/cannot cope moving forwards.
One thing to consider - if the debt is limited to a fairly small number of cards, you could try contacting each company and explaining that you are likely to begin proceedings for bankruptcy, and ask if they would be willing to consider making a settlement with you and arrange a sensible repayment plan for a reduced figure. They might totally dismiss you but they migjt surprise you with what they're willing to chop off your debt. This is what will happen if they sell your debt to a collection agency or if you go bankrupt anyway. If you are able to avoid bankruptcy in this way then it's worth considering, but not if your own wellbeing will suffer as a result.
If you have any questions I'm happy to try to answer. Best of luck.
