My wife ran up credit cards to about £60,000

My house is worth about £120.000 and to get her out of trouble we had equity of £33.000 and now owe about £50,000 with the interest. If we divorce, is she entitled to half of what's left? I am disabled with no income other than mobility allowance and medium rate of living allowance and I am 81 years old, with cancer  and arthritis.
