I little improve answer The Lucky Coder. This implementation cannot accept null values at all.

class NonNullMutableLiveData(initValue: T): MutableLiveData() {

    init {
        value = initValue
    }

    override fun getValue(): T {
        return super.getValue()!!
    }

    override fun setValue(value: T) {
        super.setValue(value)
    }

    fun observe(owner: LifecycleOwner, body: (T) -> Unit) {
        observe(owner, Observer { t -> body(t!!) })
    }

    override fun postValue(value: T) {
        super.postValue(value)
    }    
}
