What happens if you default on the instalments of a purchased property?

Dear Sir/Madam,

I wanted some legal advice regarding my property issue.

I have purchased a quarter share of a hotel room investment in a project in Dubai Marina. I have paid about 31% of the total purchase price. I have signed all the paperwork and obtained the partial property deed.

Due to the Coronavirus, I am unable to continue to make the payments required. Now the developers are saying that by Dubai Law, they are allowed to keep 25% of the total purchase price from the monies I have paid.

I want to know if there is any case law or discretion that the developers have to consider in circumstances such as mine where I want to complete the transaction but I am unable to due to not having a job and financially being able to complete the transaction.

I am trying to sell the interest but at present cannot find a buyer.

Please let me know what my legal rights are if the developer does keep the full 25% of the purchase price, do I have any legal remedies?

Thank you

Z.
