Commercial property sale?

Last yr ex2b and I bought property 50/50 since jan no contributions have been made to mortgage.I cannot afford to pay full house mortgage and this I informed the bank to see if ex2b would he hasnt.
Bank want their money.
I suggested to sol I put it up for sale as sole seller sol agreed and will deal with ex2b and paperwork. Sol said he cant say no to a sale unless he pays full mortgage and eventually will have to give me a portion of the equity or sell. Is this the best thing to do or is there another way.
The business has never been operational but a loan remains outstanding no contributions have been made to this either.
Will the bank wait for the sale or what shouldI do.
Ex2b is ignoring the situation completely.

if the property is in joint names I would get confirmation from his sol stating that he is happy for u to sell the property and reimburse you for any expenditure from the sale proceeds, otherwise he will just put a restriction on it and u will lose any maoney paid out will be lost.
inform the bank that it is up for sale, they will give you if you r lucky upto 6 months to get rid of it.
if the property is in joint names then the solicitor is under duty to pay each of u 50/50. if in his name only then you will have to hope he gives you your half.
hope this helps
kind regards
