FRONT RH DROPOUT
FORWARD FACING
DISC BRAKE FORK
CARBON FIBRE
The tip with the lawyer tab on it, ie. the bottom tip, has broken off. But the dropout still allows the full diameter of the QR to clamp square. I am inclined to file off the lawyer tab on the opposite dropout to match.
As far as I can tell, I am just missing the lawyer tab. The rest of the dropout seems to be sound.
Comments gratefully received.

"The "lawyer tab" on the bottom right of the fork reduces the likelihood that a wheel will fall out of the fork when the skewer lever is open."
Why would anyone leave a skewer lever open?
Look at how casually it says it "when the skewer lever is open".
That's NOT normal.

Re: Damaged Dropout Philosophy
Using a broken fork in any form seems like a huge false economy and an invitation for a nasty incident.
If it has sustained a break at the dropout of any type I would be very wary. I certainly wouldn't file off the other one in the interests of aesthetics!
Disc brakes also place different loads in the hub area I believe (why you can't use Ti skewers with them for example).
Buy a new fork.

well I don't think it would have been spirited away by the faeries....
so that leaves possibilities of 1) an intrinsically duff fork (if it breaks once for no good reason, why not elsewhere...?), or
2) some kind of impact damage, that may be more extensive than it appears to be.

Unless there is a good reason why the fork has sustained the damage it has, and it is absolutely clear that the damage isn't more extensive than it might be, I'd regard the fork as 'suspect'. The absence or otherwise of the lip per se wouldn't be such a major concern to me (not with a forward facing dropout and a rear mounted caliper) but it must
a) surely make it more likely that the wheel can move in the dropout if the QR isn't tight enough and
b) make it unlikely that the fork could ever be sold on with a clear conscience; it is almost certainly a wrong thing to do if you delete a safety feature from something and then sell it on as something other than 'scrap'.

Purchase from a well known internet auction site. Thinking the 'supposedly reputable' seller would not have sold them like this without at least saying in the internet listing, they might have been damaged in transit - no dropout protector.
If one of the lawyer tabs has gone, do people think it safer to remove the other one as well? I'm thinking that just one lawyer tab might be more unsafe than having none.

I should coco.

No, it's not safe if used with a disc brake. The torque created by the disc brake tends to pull the wheel from the drop-outs and the lawyer's lips is an essential safe-guard in this case.
Why not have a new one brazed on the drop-out....it's not a difficult job.

Plenty of (and I mean many, many) people forget to tighten, don't know what is sufficient clamping force or leave the lever in the open position and screw the skewer closed
I'd consider using the fork without a lawyer tab and with a disc - the dropouts are forward facing so that the direction of braking forces aren't tending to rip the wheel out of them. Obviously you'd have to be very scrupulous in clamping your skewer, and I'd probably only use one of the internal cam shimano type that clamp up nice and tight easily and don't have a squashable plastic washer.
How did the damage to the fork happen though? That might be an issue especially considering that it's a carbon fork.
