Wow, some really bad advice from folks based on one limited picture - bad foundation, water too much and lawyer up!!

Honestly, by itself, that picture does not give enough information to make any kind of professional judgement on what is going on with your house. All you can say is what you see - the very top brick has shifted/has come loose and those short pieces of frieze board have shifted. Neither of those are definitive signs of abnormal foundation performance by themselves. Either way you don't need to water your foundation every day in December (or even July). Yes, you need to keep the moisture at the foundation consistent, but everyday is a bad idea.

The mortar crack is not enough and the the frieze board pieces there are too short to be dependable indicators.

That looks like a rear patio? Look closely at the brick moving to both sides of the area pictured. Look for tapered cracks. Usually these will present around windows either as step cracks below the window sills or as tapered cracks going up the seam between the window frame and the brick. Sometimes they will show up in an expansion joint. Look at the corner frieze board connections at corners where the board is longer. At least 6 feet on each side.

If you find anything outside look inside in that area. Again look for tapered cracks. Usually they will present at window or door corners or perpendicular walls. Doors sticking or being out of square are an indicator, but usually these least reliable since doors can be poorly secured and shift on their own.

Again there isn't enough information give. To make a professional judgement, but based on the picture, I wouldn't be that worried. For the record I have 30 years experience as an inspector, realtor, contractor, etc. if you do see additional cracks like I described you could have one of the honest foundation companies come look (usually free) or pay an engineer of inspector. Feel free to reach out directly for more information or with more pictures/questions.

Better raze to the ground and start over.
