I have been using the followingphrases
but I am still not confidentthat
they are grammatically correctand sound right: "in regards with something" "in regard to" is the right way here.
"with regards to something" This is OK.
Somehow I have the feeling that "with regard to" is more normal though.
Paul Brians seems to back this up . "regarding something" This is OK, e.g. film title "Regarding Henry", etc.
I have also heard/read people using anarbitrary combination of the above(e.g. "
in regards to").
Are thosecorrect?
If yes - are they equivalentor
the usage depends on context?
It's much easier to answer your question if you put in some examples you've seen.
Anyway I hope the above is enough.
Note that there is a completely different usage "regards to" as in "give my regards to old Broadway and tell them I will soon be there" etc.

"Regarding" is better than "in regard to".
"About" is absolutely fine and good old plain English - nothing wrong with it.
Plain English is good and eminently preferable every time.
All too often people try and be clever by using fancy and/or unnecessary words.
Just say it how it is.
Awful:
In regards to With regards to Fine: About
In relation to With regard to In relation to Concerning

Even when using "with regard to", most people use it incorrectly.
Why not avoid this word altogether and say "concerning", "about" or "in the matter of", all perfectly sound and correct. "
With regards to" is colloquial and incorrect.
