under sgp law what would happen with the following case?
- A's parents stays in A's house / apartment and A's is living elsewhere (all living in SGP)
- A's sibling, B, moves in to stay with the parents
- B claims he looked after the parents during this period (can be years)
- The parents sets up will to indicate they want to give the house / apartment to B
Is this will effective since A's the lawful owner of the property?
Or would the court rule based on the fact that A was not living at the property while the parents did, hence they are the actual occupant and hence considered as de facto owners, hence the will is effective?
If there was no will, can B fight with A for the property occupied by their parents?
