How to say "distrust" in Japanese

• 疑ううたがうJLPT N3approx.Common
  godan verb, transitive verbThe verb: use it when you want to say that someone doubts, distrusts, or is suspicious of a person or thing — distrusting another's words or motives, for instance.
  僕ぼくの言葉ことばをまだ疑うたがっているんですか。↗

  Are you still in doubt about what I have said?
• 不信ふしんCommon
  nounA noun for distrust or mistrust as a feeling or state, typically directed at a person, group, or institution — public distrust of politicians, for example.
  花子はなこは不信ふしんに思おもって本当ほんとうかどうか問といただした。↗

  Hanako questioned his sincerity.
• 疑惑ぎわくJLPT N1approx.Common
  no-adjective, noun (suffix)Doubt or misgivings above all: uncertainty about whether something is true, right, or properly done. Its 'distrust' sense is secondary, so it fits doubts about a situation more than distrust of a person.
  この種しゅの事件じけんはよく疑惑ぎわくを生うむ。↗

  Events of that type generally arouse suspicion.
• 疑ぎCommon
  nounEssentially a combining element rather than an independent word: it carries the sense of doubt, distrust, or suspicion only within other words, so it is seldom the word you want for 'distrust' itself.
• 疑いうたがいCommon
  nounThe noun counterpart of 疑う: doubt, question, uncertainty, or skepticism about whether something is so. For a settled feeling of distrust toward a person, 不信 is usually the better noun.
  それで疑うたがいをさしはさむ余地よちはなくなる。↗

  That leaves no room for doubt.

For the act of distrusting use the verb 「疑う」; for the feeling of distrust toward a person or institution use 不信; 疑惑 and 「疑い」 express doubt or misgivings rather than settled distrust; 疑 is chiefly a combining element.
