**No—you cannot informally move a replacement roommate in without the landlord’s written approval.** Standard Singapore Tenancy Agreements (TAs) prohibit subletting or changing named occupants without prior consent, and doing so informally puts you in breach of contract.

### 1. Landlord Approval & Verification
* **You Can Source, Landlord Must Approve:** You and your departing friend can look for a suitable replacement, but the landlord must vet and approve their profile (NRIC/FIN, employment pass validity, and income) before they move in.
* **URA Occupancy Cap:** Under URA rules for private condos, a maximum of **6 unrelated persons** (or up to 8 only if the unit is ≥90 sqm and URA-approved) may live in the unit.

### 2. Updating the Tenancy Agreement
You do not always need to sign a brand-new lease from scratch, but the change **must be documented in writing**:
* **Option A — Formal Deed of Novation / Lease Addendum (Most Common):** All four parties (landlord, two remaining tenants, departing tenant, and incoming tenant) sign a written addendum. It formally releases the departing friend from future liability and binds the new roommate under the existing terms and expiry date.
* **Option B — Fresh Tenancy Agreement:** The landlord terminates the current lease by mutual agreement and executes a new TA with you, your remaining friend, and the new roommate for the balance period (requires fresh IRAS stamp duty within 14 days).

### 3. Practical Steps to Protect Yourselves
1. **Settle the Security Deposit Privately:** The landlord holds the original deposit until the final lease ends. Usually, the incoming roommate pays the departing friend their 1/3 deposit share directly, and you conduct a room condition check beforehand so you aren't stuck paying for the departing friend's damages later.
2. **Update Condo MCST Records:** Submit the signed addendum and new tenant's ID to the condo management office to transfer access cards and resident registration.
