Most homeowners discover this the hard way. They ask an agent, a relative, or a counselor to call the mortgage servicer on their behalf, and the servicer politely refuses to discuss the loan at all.
That refusal is not obstruction. Federal privacy rules and a servicer's own policies stop it from discussing your loan with anyone you have not named in writing. The form that fixes it is usually called a third-party authorization, sometimes a borrower's authorization or a letter of authorization, and without it almost nothing can move on your behalf.
Get free help on your side first
Before you sign anything giving another person access to your loan, talk to a HUD-approved housing counselor. Counseling from a HUD-approved agency is free to you, the counselor has no stake in which outcome you pick, and this is exactly the kind of document they review every day. You can find an approved agency through the U.S. Department of Housing and Urban Development or through the national housing counseling hotline.
And please hold on to this line. NOBODY SHOULD CHARGE YOU AN UPFRONT FEE to be your authorized representative, to negotiate with your servicer, or to arrange a short sale. Legitimate housing counseling costs nothing. A real estate agent in a short sale is paid from the closing, if a closing happens, and not a dollar before. If a stranger who found your name in a public filing asks for money in advance to speak to your lender, that is your signal to stop and tell your counselor about the approach.
What the authorization actually does
It gives a named person permission to receive information about your loan and to speak with the servicer about it. That is genuinely useful. It means your agent can confirm what the servicer is missing rather than relying on your memory of a phone call. It means a counselor can ask about programs by name. It means you do not have to be the sole relay between people who need to compare notes.
What it does not do is transfer any authority to decide. An authorized third party cannot accept a payoff, agree to terms, or sign for you. Only the borrower does that, and any document that seems to hand someone else the power to make decisions about the property is a different instrument entirely and belongs in front of a real estate attorney before you sign it.
Who you might name
Commonly the listing agent, so that the sale side of the file can be worked. Often a HUD-approved housing counselor. Sometimes an attorney. On a loan with two borrowers who are no longer living together, sometimes each names their own representative, which servicers generally accommodate.
Be deliberate about the list. Every name you add is a person who can obtain detailed financial information about you. Add the people doing the work, and no one else.
What the form asks for
Expect it to want your full name as it appears on the loan, the property address, the loan number, the name and contact details of the person you are authorizing, and your signature. Many servicers require every borrower on the note to sign, not just the one who calls. Some require a date and some expire the authorization after a set period, which is why it is worth diarizing a renewal rather than discovering the lapse mid-negotiation.
Use the servicer's own form if it publishes one. A generic letter is sometimes accepted and sometimes bounced, and a bounced form costs you time you would rather not spend.
Getting it accepted, and keeping it working
Send it the way the servicer asks, keep a dated copy, and note the reference number of the call where you confirmed receipt. Then verify by having your representative call and be recognized. An authorization that is on file but not linked to the loan in the servicer's system is a common and quietly expensive failure.
Expect to send it again. Files get transferred between departments, servicing rights get sold, and paperwork gets misplaced. This is normal, it is not evidence that you are being singled out, and the same patience applies to every other document in the package. The wider list of what a servicer will want is worth reading before you start, and the short-sale document package for Claremont sellers lays that out.
Delegating is not disappearing
An authorization is a convenience, not an exit. You should still open the mail, still read what is sent to you, and still ask your representative to summarize what changed after every meaningful call. Ask for the servicer's contact name and reference number each time so that the record belongs to you and not only to the person acting for you.
Choose that person carefully. Short sales are their own discipline and experience genuinely shows in how a file is presented, which is the argument in vetting Claremont short-sale help. Ask what they have handled, ask how they will keep you informed, and be wary of anyone who promises an approval, a specific timeline, or a particular result. No one can promise those, and the promise itself is the warning.
Two people who are not on the call
A CPA or tax professional should look at any question about forgiven debt, because the treatment depends on facts about your loan and your return that only a professional reviewing your situation can assess. A real estate attorney should look at anything affecting your liability, and at any document beyond the plain authorization itself. Nothing written for a general audience replaces either one.
Finally, hold the possibility open that the short sale is not the answer. Reinstatement, a repayment plan, a loan modification, or an ordinary sale with equity may all be better outcomes than the one you came looking for, and a good advisor will say so plainly.
For the full picture and how the options compare, start at the Claremont short sales guide, and if you have not yet made the first phone call, read talking to your lender early before you name anyone at all.

Frequently asked questions
Does signing an authorization give my agent control of my loan?
No. It permits the named person to receive information and speak with the servicer. It does not let them accept terms, sign for you, or make decisions about the property. Any document that appears to do those things is something different, and it belongs in front of a real estate attorney before you sign it.
Do both borrowers have to sign?
Most servicers require a signature from every borrower on the note. That is worth confirming early if the borrowers are separated or no longer speaking, because a missing signature stalls the whole file. A HUD-approved housing counselor can help you work out the practical sequence in that situation.
Can I revoke it later?
Generally yes, in writing to the servicer. Keep a dated copy and confirm by phone that the change was applied, the same way you confirmed the original. If revoking is tied to a dispute with the person you named, speak with an attorney before you send it.
Should I authorize a company that contacted me about my mortgage?
Be very careful. Unsolicited outreach to homeowners in default is a known pattern, and giving a stranger access to your loan details is a serious step. Nobody should charge you an upfront fee for this work. Start with free HUD-approved counseling and let a counselor look at anyone who approached you.
