Fast offering reimbursement for rent

I have a member that needs his rent paid, we sent a check on the 21st but the landlord has not received it yet and is now asking for a payment today or he will evict the member. I checked to make sure the check has not cleared and it has not.
There is no way for the rest of the bishopric to print sign and deliver a check today so I'm considering making a check out of my personal account and getting reimbursed.
Is there a reason I should not do this?

In the help center article Paying Expenses of Ward Members (item 3) it indicates that when possible payments should be made to service providers rather than individuals. So that's the best way. But it isn't an absolute rule. So if the circumstances prevent direct payment to the landlord then making payment and getting reimbursed may be needed. I would recommend including a note in the documentation for the expense giving the reason and, of course, the check for reimbursement needs to be signed by two others than yourself. I'd also try to get a dated receipt from the landlord as well to show that the check did go to the landlord.

You also should void the check that was never cashed and inform the landlord of that fact. You can void the check in MLS - the clerk can do that without having a bishopric member available, I believe.
