Paying for a deed search to find the properties the deceased father owned

Q: In order to find the properties which my deceased father owned, we need to conduct a deed search. Should the fee for the deed search be shared equally between all the heirs (i.e. the two sons and two daughters) or should the fee be shared between the heirs according to their stipulated shares of inheritance (i.e. the sons will pay double the amount the daughters pay)?

Charging the EFT charges when giving someone a loan

Q: My friend asked me for a loan of R10 000. He said that he will pay me back the R10 000 after a week. There is no extra amount that I asked him to pay over and above the R10 000. However, since he asked me to eft the amount to him through which my bank will charge me R7, I asked him to pay my bank charges i.e. to pay the R7 which my bank will be charging me to do the eft. Is it permissible for me to take the R7 from him for the eft charge?

Reciting words of durood not established in the Hadith

Q: There is a specific durood from the elders that I have found repeatedly. Yaa rabi salli wa sallim daa e man a ba dan a laa habeebika khairil khalqi kuli hi me 

Another adds the additional line of wa barik wa salim tas leeman ka theeran ka theeraa. 

It seems as is there is an emphasis of great virtue of this specific durood. Are there any virtues or specific benefits or importance of this durood?
