Ritual 81

If any one among the heirs admits that there was an obligation on the deceased to perform pilgrimage, it is not obligatory on those who think so to have the pilgrimage performed, except to the tune of their shares of inheritance.

However, if the shares of those who consider so are not adequate to meet the expenses of the pilgrimage, it is not obligatory on them to meet the shortfall from their personal properties. If a donor comes forward to make up the shortfall, or it is met in any other way, deputizing someone to perform Hajj for the deceased becomes obligatory.
