Sorry about some incoherence above - some bug interfering with the setting out of the  text!

It's not a small thing at all. It is worth it to pay an ASLOCA lawyer to send the regie a registered letter citing the specific code of obligations. if your regie does this, they'll do anything. 

Make certain this is done by registered letter and keep copies. 

Many thanks for that.I have made an appointment with ASLOCA

At least for rents, this is not usual, but not unheard of. The Code of Obligations IMHO does not contain an anwer to your question, but the landlord could include such an condition in his contract. One example I found was:

"Post office counter cash payments are causing fees at the expense of the payee that will be reclaimed from the tenant. In order to prevent from getting charged at the end, you have to add CHF 3.- to the payment."

If he has not, I see little chance that he could win in court.

It is becoming common to pay extra for paying AT the post office.

However if you pay the "pink PTT form" by E_Banking there is no extra charge.

(You pay only the figure on the PTT form)

Then can not charge oyu fees for receipts from any financial institution, unless they receive less than the rental amount contracted. So did La poste charge a fee for the payment, if so, it shoudl be on the receipt you received when you made the payment? Or if you have an account with La Poste then make sure all charges are paid by you. because payments are made with 'All charges paid by you, yours/mine, theres paid by themselves. This is usually a check/tick box on the Giro/Bulitine du versement. Again, your not responsible for there bank charges at all.

Dave, I don't think, that the information you give is correct.

On page six here, the costs are clearly listed. So if you have a red credit slip and pay CHF 1'800.00, the fee is CHF 3.55. This fee is not shown to you, but the payee does not recieve the full 1'800.00. These fees are only due, when people pay at the counter at the Postfinance.

And after a brief internetsearch, I have found no indication, that the payer has to cover those fees, except if such a rule is part of the contract.

Alan S-any chance of directing me to your internet search links?

Sure, for a "Thank poster" I do almost everything ;)

I am from Basel, so the article is in German:

http://www.ktipp.ch/artikel/d/miete-am-postschalter-bar-eingezahlt-muessen-mieter-spesen-der-post-uebernehmen/

Ktipp is a consumer protection organisation.

"Nein. Ihr Vermieter hat Ihnen Einzahlungsscheine geschickt; das ist üblich. Damit nimmt er aber in Kauf, dass Sie die Einzahlungsscheine so verwenden, wie es eben auch üblich ist - für eine Bareinzahlung am Postschalter.

Mit anderen Worten: Durch sein Verhalten geht der Vermieter ganz bewusst das Risiko ein, dass ihm wegen der Bareinzahlung Spesen entstehen; diese Spesen kann er nicht von Ihnen einfordern."

(My) translation: No, the landlord has sent you bills and with that he has to accept, that you use them in normal way, which includes paying in cash at the counter.

In other words, he accepts the risk, that he receives less if the tenant pays by cash deposit.
