# Estate Administration - Document Upload Guide

## Overview
Each estate case task now supports document uploads. Users can upload supporting documents for each step of the estate administration process.

## What Was Added

### 1. Database Field
- `EstateTask` model already has `document_path` field for storing uploaded documents

### 2. View Updates
**File**: `resources/views/admin/estate/show.blade.php`

Each task now displays:
- **Document Upload Section** with a light blue background
- **Current Document Display** (if already uploaded) with download link
- **File Upload Form** allowing PDF, DOC, DOCX, JPG, JPEG, PNG files (max 10MB)
- **Upload Button** to submit the document

### 3. Controller Method
**File**: `app/Http/Controllers/EstateController.php`

Added `uploadTaskDocument($caseId, $taskId)` method that:
- Validates the estate case exists
- Validates the task belongs to that case
- Validates the uploaded file (PDF, Word, or image formats, max 10MB)
- Deletes old document if exists
- Stores new document in `storage/app/estate-documents/` directory
- Auto-sets task status to "in_progress" when document is uploaded
- Returns success message

### 4. Route
**File**: `routes/web.php`

New route added:
```
POST /admin/estate/{caseId}/task/{taskId}/upload
Route name: admin.estate.task.upload
```
