Porta
porta · noun, feminine · a gate; the way in
Every co-marketing agreement enters through one gate — checked, decided and recorded before it's let in.
In the castrum
Nothing entered except through a gate.
A Roman legion on the march built a fortified camp — a castrum — at the end of every day, and it built it to the same plan every time. A ditch and a rampart closed the camp on all four sides. Four gates broke the wall: the porta praetoria facing the enemy, the porta decumana at the rear, and the two portae principales at either end of the camp's main street.
Those gates were the only way in. They were guarded day and night, and after dark no one passed without the watchword. Whatever was inside the walls had come through a gate, under someone's eye.
In your company
Agreements between loan officers and referral partners are where RESPA Section 8 risk lives. Castrum Porta makes every one of them come through the same gate: submitted the same way, checked against the same standard, approved by a named person, and recorded with the reason it was let in.
How it works
Four steps. Every time.
- Accessus
Approach
Loan officers and realtors submit through one shared link — no account needed. Section 8 flags run before they press send.
- Interrogatio
Challenge
Requests arrive pre-flagged. Your reviewer researches fair market value without leaving the request.
- Transitus
Pass
Nothing advances without a required attestation. Denials need a documented reason. Signatures are collected in the app.
- Commentarius
Record
Every agreement, document and decision is archived with its audit trail — kept in one place for when examiners ask.
Step by step
See what happens at each step.
The screens your team and your loan officers actually use.
Easy for every loan officer.
No accounts, no training, no IT ticket. Share one link — loan officers and realtors submit co-marketing and sponsorship requests from any browser. Section 8 flags run before they press send.
What's inside
Castrum Porta, piece by piece.
One public submission link
LOs and realtors submit co-marketing and sponsorship requests from any browser. Only your compliance team needs accounts.
Section 8 flags before submit
Compliance checks run on the form itself, so problems are caught — and acknowledged — before a request reaches review.
AI fair-market-value research
AI-assisted research pulls comparable market rates, with cited sources, into the review — for your reviewer to evaluate.
Attestation on every advance
A reviewer must attest before a request moves to signatures, and every denial needs a written reason. Both are enforced on the server, not just on screen.
Castrum-reviewed agreement templates
Agreements are generated from Castrum's standard templates, or from your own template once Castrum has reviewed and approved it.
Due-diligence reviews
Active agreements come back up for scheduled re-review, so an approval doesn't quietly go stale.
The rest of the castrum.
Every product shares the same review queue, audit trail and records. See the platform.
