My brother and I will inherit my step father's property once probate is finalised and the will is executed. we are both currently living in the house on the property. my brother owns a bird/pet supply business that is using part of the property for aviaries and bird breading. My question is, can I, being future part owner of the property charge his business rent for the area taken up by the aviaries even though the will has not been executed, or would any rental charged go to the deceased estate? The space taken up by the aviaries is 300 sqm.
