Inheritance

Q: My sister's husband passed away. He had a house on mortgage which she sold and received some money after paying off the loan. He has one other property. Please advise how this share is done as he left behind his parents, a son and a wife. 

Reciting toilet duas when going to the bathroom to make wudhu

Q: I have a question regarding the duas which are recited before and after going to the bathroom ("Allahuma innee a'udhu bika minal khubuthi.." and "ghufranak, alhamdulillahilladhi adhaba 'anni..").

Should these duas be recited if my purpose for entering the bathroom is to do wudhu in the sink or to take a shower? Or is it only if I enter the bathroom for going to the toilet?
