You can lose deposit, house if you default

I resolved to buy a house from a Government institution six years ago following its pocket friendly cost. The sale agreement stipulated that I pay a deposit then settle the balance in installments before I am furnished with the legal ownership documents.

However, I defaulted for some years after my wife fell sick and I was not in a position to pay the installments over a certain period. Recently, my name was among some that were published in a mainstream newspaper for defaulting and were threatened with repossession should we not settle our dues within a specific time frame. The reality is that I am still spending a lot of money on paying medical bills for my wife and may not settle the dues as instructed. Is it legal for the house I bought to be repossessed?
