How can i add singlge quote in calculate field?

There is example of my code:

IF

[Correspondence Name] == 'House Registration Certificate's Address' THEN [Address Preview1]

ELSEIF

[Correspondence Name] == 'Living Address' THEN [Address Preview2]

ELSEIF

[Correspondence Name] == 'Place of Work' THEN [Address Preview3]

ELSEIF

[Correspondence Name] == 'Commercial Registration Address' THEN [Address Preview5]

ELSEIF

[Correspondence Name] == 'Business Address' THEN [Address Preview6]

ELSE 'House Registration'

END

I can't use 'House Registration Certificate's Address' because it has  's  ,so what should I do now.
