What is the proper way to address the check that is being given as a gift to the couple?

Eliminate the cheque and put cash in an envelope with a card.

You make it to Mr ad Mrs >>>>>
It is addressed to the couple

Hi, chuck, most banks don't accept double endorsed cheques nowadays. So your idea is not very good.

I would have said that too, but in my neck of the woods, I deliver the cash before the wedding,

I'd say money or gift cards is best.

I would not go with cash. I have known of cash to go missing at weddings.

Why not just write a cheque out to Mrs. Smith, or Mr. Smith. On the reference line, put "Sam and Bev's Wedding'.

Unless they have a special account set up, you can't write a cheque to 'sams and bevs wedding'. And double endorsed cheques are highly suspect as I said.

I think ALL of the checks that my husband and I got for our wedding were made out to mr. and mrs. We didn't have any trouble at any of the banks that we deposited. I've never know it to be a problem for a married couple.

I'm sorry, that didn't come out very clear.

What I meant was write the cheque out to either him, or her.

On the line at the bottom where you put what the cheque was for, put wedding.
Or nothing at all.

DO NOT GIVE CASH! I am in the industry - you would be surprised/horrified to know how often envelopes "disappear" at wedding receptions. Give a check, that way if they do not receive it a stop payment can be made.

As for making the check out - make it out to him. Some banks do not allow endorsement by 2 people. It may be several weeks before she changes her name, if at all. Like Jake2008 said, put both their names in the reference line.

I think you could write both of their names on it, then both of them endorse it and deposit it in the bank. Not a problem. I've never had a problem with that before, giving nor receiving. I agree that cash is risky, too. Another option is to put the gift on a prepaid charge-card like a Visa gift card. Then they don't have to deposit it.

Or if you really want to give cash, hand it to the groom directly at the reception, or give it to someone else trusted like the mother of the bride and let her know it contains cash so it can be handled with care.

To the parents who spent thousands on the wedding, you address it to them..
Kidding.
Why not think of some other way to give the money because there is no safe way to ask anyone what to do .I'm sure the bride has ideas of where to put it and I am sure the groom does too. My personal account.

Since there is no nice way to ask I agree with the above,take a chance with Mr. and Mrs.

Yes, I agree with jjwoodhull. You should write it out to him. If you write it out to her and she doesn't change her name then she won't be able to cash the check. Also, to cash a check, you need to show photo ID and if her name on her ID doesn't match the check name then it does no good then either. Just to be safe write it out to him and on the envolope write both of their names so they know it is to both of them not just one.

You can make it out to: " Ivan or Alison Wallace" - just like that, with the "or" on the "pay to the order of" line. That way, only one person has to endorse the back - although, I worked in banking for years, and had no problem with double endorsements, if both parties were present. :)

The OP didn't say anything about sending the bride and groom on a honeymoon.

But you can send them if you like just send the reservations details to me.

Put both of their names on rhe cheque.
