Therefore vs. There For
“Therefore” is a single adverb that links a result to a reason. “There for” is not an alternative spelling; it is ordinary two-word syntax, often seen in expressions such as “be there for someone.”
Use “therefore” as one adverb meaning “for that reason.” Write “there for” as two words only when the sentence independently needs “there” followed by “for,” as in “be there for someone.”

Quick tests
Decision test
Can the expression be replaced by “for that reason” without changing the sentence meaning?
If yes: Use “therefore.”
If no: If “there” and “for” each perform their own grammatical role, write “there for.”
Caveat: Do not assume every “there for” sequence is the support idiom; ordinary syntax can place the two words together for other reasons.

“There” refers to place and “for” begins a duration phrase.
