Write to admin@wirasat.com. There are three reasons to get in touch, and the fastest route differs for each.
A result looks wrong
Use the error report form. It captures the heirs, the school and what you expected, which is everything needed to reproduce the case. This is the most useful thing anyone can send us.
You are a qualified scholar
The calculator is waiting on review in each of the four Sunni schools, and there are specific open questions rather than a vague request to "check it". If you are qualified to rule in any of them, please write — the review is paid work, not a favour, and your name and credentials would be published alongside it.
Anything else
Corrections to a guide, a request for a worked example, a question about the method — all welcome. Please include the page you are writing about.
What we cannot do
We cannot issue a fatwa, act as your lawyer, or advise on a specific family dispute. For a real estate division you need a qualified Mufti, and in most countries a lawyer as well. See the disclaimer.
