You Don't Have to Pay Your Deposit in One Lump Sum, the Right to Three Installments
A move into a new Munich apartment already stacks up moving costs, furniture, and often two overlapping rents, so being told to hand over a full three-month deposit on signing day can genuinely break a family's budget. German law doesn't actually require that. Under Paragraph 551 of the Bürgerliches Gesetzbuch (BGB), Germany's civil code, a landlord cannot legally demand more than three times the monthly cold rent (Kaltmiete) as a deposit in the first place, and separately, a tenant has the legal right to pay that deposit in three equal monthly installments, the first due together with your first month's rent, not at contract signing itself. A rental contract clause that tries to rule this out or force a lump-sum payment is simply invalid under German law, it doesn't need to be individually challenged in court to lose its effect. The one thing to watch is that falling behind on the installments themselves by an amount equal to two months' cold rent can give a landlord grounds for an extraordinary termination, so the right to pay in installments isn't a right to pay late.
The Official Rule
A Munich landlord asking for the full deposit, often the maximum three months’ cold rent, in a single wire transfer before handing over the keys is common enough that many tenants simply assume it’s mandatory. It genuinely isn’t, and the two protections involved are worth knowing separately.
First, the deposit amount itself has a hard ceiling. According to Section 551 BGB, Germany’s civil code, a landlord cannot demand a security deposit exceeding three times the monthly cold rent, the base rent excluding utility advances or flat-rate charges. Any agreement asking for more than that cap simply isn’t enforceable.
Second, and separately, a tenant has the legal right to pay that deposit across three equal monthly installments rather than in one lump sum. The same provision states that the first installment falls due at the start of the tenancy, together with the first rent payment, not any earlier. The remaining two installments follow month by month after that.
| Installment | When it's due |
|---|---|
| 1st (one third of the total deposit) | Start of the tenancy, together with the first rent payment |
| 2nd (one third of the total deposit) | Together with the second month's rent |
| 3rd (final third of the total deposit) | Together with the third month's rent |
A lease clause that tries to override this doesn’t hold up. Per mietrecht.org, a landlord cannot lawfully exclude the right to installments in the rental contract or require an upfront lump-sum payment as a condition of signing. If a lease does contain such a clause, it’s simply invalid, a tenant does not need to fight it in court individually for it to lose its legal effect, the statutory right applies regardless of what the contract says.
There is a genuine limit, though, and it’s worth taking seriously. VON RUEDEN | HEYSE, a Berlin law firm specializing in tenancy law, notes that once a tenant falls behind on the deposit installments by an amount reaching two months’ cold rent, the landlord gains the same grounds for extraordinary termination that would apply to unpaid rent itself. The installment right spreads out the payment timeline, it doesn’t grant open-ended flexibility about actually paying it.

What Real People Say
Tenant guides and forum discussions about moving into a new apartment consistently flag the same surprise: many renters simply pay the full deposit at once because the landlord’s request implies it’s required, without realizing the installment right exists at all. The people who do use it describe a straightforward process, a short written note to the landlord stating the intent to pay in three installments, and then treating each installment with the same punctuality as rent, since the two-month arrears threshold for termination is real and worth avoiding.
Step by Step
- Confirm the total deposit doesn’t exceed three months’ cold rent, that cap applies regardless of what your contract says.
- Notify your landlord in writing that you intend to pay the deposit in three installments, this doesn’t require their approval.
- Pay the first installment at the start of the tenancy, alongside your first month’s rent, not before.
- Pay the remaining two installments in the following two months, each alongside that month’s rent.
- Treat every installment as seriously as rent itself, falling two months’ rent behind on the deposit can trigger the same grounds for extraordinary termination.

FAQ & Common Pitfalls
Does my landlord have to agree to installments, or can they insist on a lump sum?
You don't need your landlord's agreement, this is a right you already have directly under Section 551 BGB, regardless of what the lease says. If your rental contract includes a clause requiring the full deposit upfront or explicitly ruling out installments, that clause is invalid, it doesn't override your statutory right, and you don't need to challenge it in court for it to lose effect. In practice, simply informing your landlord in writing that you're exercising your right to pay in three installments, and then doing so, is enough.
When exactly is each installment due?
The first installment is due at the start of the tenancy, alongside your first rent payment, not on the day you sign the contract. The remaining two installments follow in the next two months, each alongside that month's rent. Spreading it this way genuinely changes your cash flow in the first month of a move, when moving costs, a first Kita fee, or overlapping rent on a previous apartment can all land at once.
What happens if I fall behind on the installments themselves?
This is the real limit on the right. If you fall behind on your deposit installments by an amount that reaches two months' cold rent, your landlord gains the same grounds for an extraordinary termination that apply to falling behind on rent itself. The right to pay in three installments is a right to spread the cost, not a right to delay it indefinitely, so treat each installment with the same seriousness as a rent payment.
