Afternoon Shelley,
I can only assume that the court awarded the unit to your mum where no contest took place. There should be an update of the ownership hence it's good to check with HDB if your mum is required to fulfill the MOP.
As to selling the unit back to HDB might not be a smart move, if HDB allows the sales. Release it into the market can definitely fetch better returns.
If you are looking at buying from HDB, it would depend in how many subsidized unit your mum has enjoyed. If she's eligible, she would need to purchase it with her child who is under her custody. This might be an issue as if you are posting this question, I would assume that most of you are above 21 years of age. You might have some other plans of your own and implication can take place later. Else she can purchase resale unit from open market.
Do feel free to contact me if you require further assistance.
