The structures answer an estate question
HDB describes joint tenants as holding the flat together without separate shares, while tenants-in-common hold stated shares. The practical difference becomes most visible on death: survivorship operates for joint tenancy, whereas a tenancy-in-common share forms part of the deceased owner’s estate. A will does not convert one structure into the other. HDB help on manner of holding.
Contribution and legal share are not identical
CPF use, cash payments and loan responsibility should be documented, but they do not automatically rewrite the registered holding. Co-owners should compare the intended legal shares with contribution records and estate plans, then obtain advice where the facts conflict. The application is not a shortcut for resolving a dispute. HDB help on manner of holding.
The form supports several directions
HDB’s form allows conversion from joint tenancy to tenancy-in-common in equal or unequal shares, the reverse conversion in stated cases, and changes to existing proportions. Proposed fractions must total one, or percentages 100%. Every owner should check the completed table before signing. HDB ownership-change hub.
Plan for the wider legal and financing effects
A change in holding can interact with financing, CPF use, stamp duty, estate planning and professional work. Ask HDB what documents apply to the actual flat and obtain advice where the ownership outcome is consequential. Do not treat a holding-type request as a purely clerical rename.

Update the linked estate file
After approval, retain the new holding record with the flat purchase documents, CPF and loan statements, wills, nominations and any family agreement. Tell the relevant adviser which structure is actually registered. A private note expressing an intention is not the same as an HDB-approved change. HDB holding-or-proportion service.
Choose the HDB service that matches the legal change
HDB separates a change in manner of holding or ownership proportion from three different processes: a change of flat ownership not through sale, a resale of part-share, and adding or removing an occupier. Begin with the registered owners and the intended end state. If a person is entering or leaving the title, or consideration is changing hands, do not force the case through a holding-type request merely because the family also wants different shares. Use the dedicated holding-or-proportion service only when that is the actual legal change being requested. HDB holding-or-proportion service.
Use the form’s exact conversion direction
The form distinguishes joint tenancy to tenancy-in-common in equal shares, joint tenancy to unequal shares, tenancy-in-common in equal shares to joint tenancy, and stated changes to an existing proportion. Select the direction that matches the registered starting position and proposed result. It provides fields for up to four current owners and says no space should be left blank. Copy names and NRIC details from the operative records, mark inapplicable fields as the form directs, and have every owner review the same completed version before signatures are collected. HDB holding-or-proportion service.
Test a four-owner split
Four owners want tenancy-in-common shares of 40%, 30%, 20% and 10%. Their worksheet verifies that the total is 100%, identifies how each share fits the estate plan, and records every owner’s consent before the form is filed. The percentages are illustrative, not a recommended allocation.
Only an occupier is changing: Use HDB’s occupier route instead; this form changes ownership holding. A divorce, death or dispute is involved: Obtain case-specific legal and HDB guidance before signing.
