Co-Tenant Bond NT — Splitting and Refunding Shares

Share houses, defence households with rotating personnel, and student rentals all create the same problem: multiple tenants on one bond, and sooner or later one of them wants out while the others stay.

How the Act Splits the Bond

Section 33 of the Residential Tenancies Act 1999 sets a simple default: co-tenants hold the security deposit in equal shares unless the tenancy agreement or bond receipt specifies different proportions.

That means if three tenants paid a $1,800 bond and neither the tenancy agreement nor the receipt records individual contributions, the Act deems each person's share to be $600 — even if one tenant actually paid $1,000 and the other two paid $400 each. The receipt is one place to record proportions. If neither the agreement nor the receipt specifies them, the statutory default applies.

This is why the receipt matters so much at the start of the tenancy. Section 31 requires the receipt to show each co-tenant's share. Getting this right up front prevents disputes when someone leaves.

What Happens When a Co-Tenant Leaves Mid-Lease

The total bond held in trust by the landlord remains intact until the entire premises are vacated. The landlord does not refund one person's share when they move out and the others remain.

Instead, the standard process works like this:

1. The outgoing tenant and the incoming tenant agree privately on the bond share. The incoming tenant reimburses the outgoing tenant for their portion.
2. Both tenants execute a formal assignment document transferring the outgoing tenant's bond interest to the incoming tenant.
3. The landlord updates the tenancy agreement records to reflect the new tenant and their assumed bond share.
4. The landlord issues an updated receipt or acknowledgement showing the current tenants and their proportions.

The bond money itself does not move. It stays in the landlord's trust account. The assignment is a transfer of the legal interest, not a physical transfer of cash.

The Landlord's Role

Your obligations in a co-tenant change are administrative:

• Update your records. The tenancy agreement, the bond receipt records, and the condition report sign-off should all reflect the current occupants.
• Do not refund the outgoing tenant directly. The outgoing tenant's reimbursement comes from the incoming tenant, not from the bond. If you release part of the bond mid-tenancy, you have reduced the security you are entitled to hold under Section 29.
• Issue clear paperwork. A written acknowledgement of the assignment — showing who left, who arrived, the bond amount unchanged, and the new proportional split — protects everyone.

Common Problems

The most frequent dispute arises when a tenant leaves, gets no reimbursement from the replacement, and then contacts the landlord demanding "their share" of the bond. The landlord's answer is correct but unwelcome: the total bond stays in trust until vacant possession of the entire premises, and the private financial adjustment is between the tenants.

The second problem is when the proportions were never documented. If three tenants each verbally agreed to pay different amounts but the receipt shows a single lump sum without names or shares, Section 33 deems equal thirds — and someone ends up disputing what they "actually" paid.
