Maintaining ownership and responsibilities
The ownership register links shares, value quotas and people. It distinguishes ownership from use and from responsibility for invoices, correspondence and voting.

Open the community and check the shares and quotas.
Check the people behind a share, including joint ownership or several units belonging to the same person.
Check the roles for invoices, post and voting; they need not lie with the same person.
Record a change of owner with "Record sale". Purchase contract, transfer of benefit and risk and land register entry are separate data; ownership changes only with the recorded land register entry.
Record each unit's use: «owner-occupied», «rented» or «vacant». If a lease exists on the unit, ImmoFlow shows it as rented with the tenant automatically; without one, add it with «Add lease» in rental management.
If several people own a unit, choose joint ownership (no shares) or co-ownership in fractions with a share per person adding up to exactly 1 (e.g. 1/2 and 1/2). Either way the unit has one vote; the contribution bill goes to the recorded billing recipient, otherwise to all owners together. All owners of a unit are invited unless they recorded a common representative.
Record the community's officers in the overview with «Add officer»: chair of the assembly, committee, auditor, manager or delegates, each with a person or company and a term. An ended office stays as history.
