Yes -- I insert the amount and the time.  And because I work referrals only, I have some additional additions. For example:

I have inserted language (much like a relocation company) stating that if the receiving company is not performing, I may pull the referral and place it with another company.

I'm pretty lax and more often than not I don't send the referral fee until they are under contract.  And, then yes, all filled out to standards.

Yes to both.  I like Gary Coles (International Referrals) idea that if they are not performing, I can pull the referral back.

Yes both signatures.  I agree with Gary if you are doing this more consistently a more restrictive addendum may be necessary.

Agents need to sign, and if not the Broker, then the Broker needs to sign the agreement.    The length of this referral needs to be on it also.

Tony and Suzanne - Yes, get all the signatures you can to document, specify the length, and verify the referral agreement.

 Good Wednesday morning Tony and Suzanne Marriott, Associate Brokers . Interesting question and I did like the answers.

Tony and Suzanne Marriott, Associate Brokers if it is agent-to-agent referral, both agents should sign that. Not sure if I'd really need my broker's signature on that.

Yes.  Always.

Absolutely...more info the better

Tony and Suzanne Marriott, Associate Brokers Yes, it makes it more official. Specifying the referral fee is a must so there are no problems later on when the property closes.

Yes, but, not always, especially if it is a very ''cold'' lead I'd warm it first. Trust and my reputation means more to me than a signature. 

I do, I have had some troubles in the past.

yes.... 

Our forms call for both signatures and when I accept one generally those forms require both signatures.

Yes, we have a written referral agreement form that requires brokers' signatures. 

No. I have documented the referral fee with the referral agent but the brokers have not been asked for anything.

Yes to the amount the time line hasn't crossed my mind.

Yes and yes. Ours are 1 year, renewable.

The amount yes.  Always a good idea to get it in writing.

I email to the person what the commission rate will be.

It does not have an expiration.  I call the person right away probing for seriousness. If we have a dialogue I send a referral agreement within the week.

No, we are able to do this on our own.
