The sharers must of course, unless excluded, be all satisfied before anything is taken by the residuaries. But the sharers may not only exhaust the property; there may not be enough to satisfy all the claimants. Thus, if a man died leaving a wife, a mother and two daughters, the shares are one-fourth, one-sixth and two-thirds, and the sum of the shares being greater than unity, they cannot all be satisfied. The difficulty is met by decreasing the shares rateably, in other words, by increasing the common denominator of the fractions so as to produce unity; hence the process is called the "increase." The converse case arises when the shares of the sharers do not exhaust the property, but there are no residuaries to take what remains. It has been doubted whether the residue does not fall to the government as _bona vacantia_. But it is now settled that the surplus is to be divided rateably amongst the sharers in proportion to their shares. The process is called the "return." The husband and the wife are excluded from the benefit of the return. If there are no sharers, the whole estate will go to the residuaries. If there are neither sharers nor residuaries, it will go to the (so-called) distant kindred. Their claim is strong on equitable grounds, as some of them are very near relations; such, for example, as a daughter's children or a sister's children. Nevertheless their claim has been doubted, and it must be admitted that there is no very clear ground upon which It can be based. They are not mentioned as sharers in the Koran, and it is not very clear how, as cognates, they could have been recognized by any ancient Arabian custom. However, their claim is now well established, and, in default of both sharers and residuaries, they succeed on a plan somewhat resembling that on which male agnates are classified as residuaries. If all the claimants fail the property goes to the government, but there is one peculiar case. Supposing a man dies leaving a widow, or a woman dies leaving a husband, and no other relative. There is then a residue and no one whatever to take it, as the husband and wife are excluded from the return. Strictly speaking, it would fall to the government as _bona vacantia_, but the claim is never made, and would now be considered as obsolete, the husband or wife being allowed to take the property.
